For reference, this was several years ago- 2015 or thereabouts. The FreeBSD project has since added or improved various security features (or made them more accessible) directly as a result of the work from and/or the pressure exerted by HardenedBSD.

This was not the case early on, and to my memory, in the early days of HardenedBSD, the relationship between the two groups could have generously been described as acrimonious. For an example, see the ASLR-on-FreeBSD debate.
